Specification of Letters Patent.

Patented May 25, 1920.

Application filed November 16, 1917. Serial No. 202,331.

To all whom it may concern:

Be it known that I, JosErH M. Mnnnow,

' a citizen of the United States, residing at Hartford, in the county of Hartford and State of- Connecticut,.have invented certain new and useful Improvements in Linings for Packing-Boxes; and I do declarethe following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part.

of this specification, and to the characters of reference marked thereon.

This invention relates to lining for pack- 'ing boxes. To insure the preservation of many different kinds of produce during periods of its storage or transportation, it is desirable that it be inclosed in a manner to exclude moisture. WVooden boxes possess many qualities essential to packing or shipping receptacles but for purposes inti' -mated are not sufficiently impervious to moisture unless especially prepared against it. The object of the present invention is the provision for boxes, preferably made of wood, of a moisture proof lining applied in a simple manner involving economical use of material and requiring few cemented joints.

v In the accompanying drawings,

Figure 1, is an isometric view of parts entering into the make-up of a receptacle including features of my invention, said parts being shown in separated relation to-clearly indicate their order of assemblage.

Fig. 2, is a plan view of a sheet of material shaped to form the main folded part of the lining as it is shown in Fig. 1, the lines of fold being located-substantially as indicated by dot and dash lines.

Fig. 3, is a plan View of the sheet material shown in Fig. 2, in partly folded condition.

Throughout the several figures of the drawings like characters of reference designate' like parts. Furthermore 1t will be noted that Figs. 2 and 3, are drawn to a slightly smaller scale than Fig. 1.

While any suitable moisture proof material may be employed to form the lOOX'llIling herein referred to, a. ,mater1al found to be particularly adapted for the purpose, is made up of paper coated with tar or similar substance and reinforced with a fabric of the nature of cheese cloth, the latter causing the finished product to offer considerable reslstance to tearing.

Referring to the drawings,-the numeral 3, designates in a general way that part of a box which includes the bottom 4, sides 5 and 6, ends 7 and 8, and the reinforcing cleats 9. The lining for this part of the' box 15 formed from a single sheet of moisture proof material as 10, which when foldedalong the lines indicated in Fig. 2, as-

sumes the form in which it is shown in Fig.

l, the bottom, sides and ends, designated respectively by 12, 13 and 1, 1, and'15 and 16, corresponding to like parts of the box andconstituting five walls of a right prism. The corner sections 17,18, 19 and20, as the sides and ends are turned angularly from the bottom, close into triangular parts which may, whenthe sides and ends are at substantially right angles to the bottom, be 1 turned or folded in overlapping pairs upon the sides 13 and 14:. In this relation the edges at the open end of the prism formed are flush or in the same plane, and include the entire marginal'portion of the original blank. This marginal portion is slightly out at the corners 21, and folded as indicated to form a flange 22, preferably of suitable width to extend across the rim of the box-and extended from edges which define a sixth wall of the right prism above mentioned. From the fact that two of the folded corner sections are added to each side when folded as shown, it will be apparent that the flange formed of the folded edges is, at the sides, of several ply thickness, while at the ends it is of but one ply thickness. Inasmuch therefore as this flange forms the contact surface to which a top sheet of moisture proof material, as 25, is cemented, it is desirable to increase the thickness of the end flanges to make them flush with the side flanges. For this purpose, equalizing or spacing pads 26. and 27, are provided. They may as shown comprise pieces of material, like that of the top and body lining, folded into several ply and secured into place by films of moisture proof cement having areas of the outlines indicated at 28 and 29. Small equalizing pieces 30, may if required be cemented into the corners is turned outward over the rim of the box, the idea being to equalize the thickness of shipment,

the folded lining which projects over and around the rim or ed e of the box before the top cover of the ining is placed and cemented. Moisture proof cement com prising a film 31, having the outline indicated, is next to secure the top sheet 25,

after which the box cover 32 is nailed or In practice the described lining is first cut in a rectangle and folded about a suitable form to produce the principal part of the lining of just the shape and size to pass into the box to be lined, with the sides all around projecting outside the box to a distance at least'equal to the thickness of the edge or rim. A slight cut made in the lining at each corner permits the projecting portion at each side to be folded over the edge or rim of the box. The spacing or equalizing pieces are then cemented in place, the contents of the box secured therein, and the top lining cemented to the part of the lining extending over and around the edge or rim of the box and to the equalizing pieces. Finally. the box cover proper is secured to the box in the usual manner. Should any surplus edges of the lining extend outside the box'after the cover is fastened they may be trimmed ofl flush with the outside. It will be seen that the main part of the lining of impervious material is integral by virtue of its foldings and that theequalizing pieces and top cover are cemented together and to the lining in a manner to hermetically seal the package. For ocean a package thus made up and sealed has in practice been found to be very satisfactory.

It will be understood that the foldings of the lining will vary in form in boxes of different roportions and in some forms of boxes t e spacing or equalizing pieces will not be needed except at the corners, in each of which a small equalizing pad may be placed. If the box is of considerable size it is deemed expedient to nail or otherwise secure the lining to the interior of the box at various points.

Having thus described my invention what I claim and desire to secure by Letters Patent is,

1. A box lining including a rectangular sheet of material folded to form both a seamless covering for the bottom and sides of a boxanda flange to extend over the rim of the box.

2. A box lining including a sheet of material folded to form a seamless open ended receptacle having a flange co-extensive with and-extended outwardly from the edge of the open end, and a second sheet of material having its margin substantially coincident with the plane of the. flange whereby the superposed margin and flange may be secured between the rim of a box and its cover.

3. A box lining comprising a sheet of material folded to form five walls of a right prism and a flange co-extensive with and extended outwardly sixth wall of the the sheet being from edges defining a prism, the entire margin of included in said flange, and

a second sheet of material constituting said sixth wall and having a margin overlying the flange whereby the superposed margins of the two sheets may be interposed between the rim of a box and its cover.

In testimony whereof, I have signed my name in the presence of two subscribing witnesses.

JOSEPH M. MERROW.
